Earthquake Engineering For Dams And Reservoirs

Earthquake Engineering for Dams and Reservoirs is an invaluable source for any engineer, or designer, tasked with building, retrofitting or maintaining dams in all seismically active regions to make decisions on the type of dam structure required for new projects and understand the issues that face existing dams and how to mitigate them.

The hazard posed by large dams has long been known. Although no concrete dam has failed as a result of earthquake activity, there have been instances of significant damage. Concerns about the seismic safety of concrete dams have been growing recently because the population at risk in locations downstream of major dams continues to expand and because the seismic design concepts in use at the time most existing dams were built were inadequate. In this book, the committee evaluates current knowledge about the earthquake performance of concrete dams, including procedures for investigating the seismic safety of such structures. Earthquake Engineering for Concrete Dams specifically informs researchers about state-of-the-art earthquake analysis of concrete dams and identifies subject areas where additional knowledge is needed.

Dams and Earthquakes deals with the association of earthquakes and large artificial lakes, particularly on the part that pore pressure plays in inducing earthquakes. The book also contains methods for recording seismic activity, before, during, and after the filling of reservoir dams through the installation of a network of portable seismographs. The text assesses the parameters and macroseismic effects of the Koyna earthquake in India in December 1967, as well as the instrumental and macroseismic data showing that the Koyna earthquake is a multiple seismic event. The book investigates the geology, hydrology, and seismicity of seismic reservoir sites, including three cases of induced seismicity after fluid injections in deep wells. A possible correlation between the reservoir level or volume of the injected fluid and the tremor frequency exists. The characteristic seismic features of reservoir associated earthquakes can reflect changes in the mechanical properties of rock masses near the reservoirs. The book also investigates the part played by increased pore-fluid pressures in triggering the earthquakes at Denver, Rangely, Kariba, Kremasta and Koyna. The UNESCO Working Group on "Seismic Phenomena Associated with Large Reservoirs" recommends the adoption of a two-phase planning in instrumental studies and surveys at sites to be used for large reservoirs. The book can be beneficial for meteorologists, environmentalists, geologists, civil engineers, structural engineers, or for officers of river and lake authorities.

A comprehensive guide to modern-day methods for earthquake engineering of concrete dams Earthquake analysis and design of concrete dams has progressed from static force methods based on seismic coefficients to modern procedures that are based on the dynamics of dam–water–foundation systems. Earthquake Engineering for Concrete Dams offers a comprehensive, integrated view of this progress over the last fifty years. The book offers an understanding of the limitations of the various methods of dynamic analysis used in practice and develops modern methods that overcome these limitations. This important book: Develops procedures for dynamic analysis of two-dimensional and three-dimensional models of concrete dams Identifies system parameters that influence their response Demonstrates the effects of dam–water–foundation interaction on earthquake response Identifies factors that must be included in earthquake analysis of concrete dams Examines design earthquakes as defined by various regulatory bodies and organizations Presents modern methods for establishing design spectra and selecting ground motions Illustrates application of dynamic analysis procedures to the design of new dams and safety evaluation of existing dams. Written for graduate students, researchers, and professional engineers, Earthquake Engineering for Concrete Dams offers a comprehensive view of the current procedures and methods for seismic analysis, design, and safety evaluation of concrete dams.

Geotechnical Engineering of Dams, 2nd edition provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. The main emphasis of this work is on embankment dams, but much of the text, particularly those parts related to g

This guide assesses the seriousness of seismic risk and proposes criteria for earthquake safety evaluation of existing UK dams. It relates specifically to the safety of UK dams and reservoirs under seismic loading although it should also be useful in the design of new dams. The guide is relevant to all forms of dam construction.

Discusses, in a unified manner, the theoretical and practical aspects of the seismic behavior of all types of concrete and embankment dams. Treats general problems of seismologic engineering, particularly the origin and tectonic mechanisms of natural and induced earthquakes, and outlines procedures for determining dynamic loadings and evaluating the seismic response and risk of dams.
